I raised a few hogs for meat.
They all had a lot more hair to start with.
They had to be dunked into a drum of hot water to loosen the hair enough
to be scraped off. A long slow tedious process.
How many kitchens have dedicated hog hair scrapers? I have 2.
If I missed some (and I always did) I would burn them off.
If you do that, be sure to burn it outside. The smell is unpleasant.
Meat will taste great though!
